Is it pedagogically sound to pretend that (1) only Africans were enslaved (ignoring the encomienda is especially ludicrous) and (2) that the descendants of African slaves were somehow of purely African ancestry?
There are two issues: Who was sold into slavery? and What do you call their descendants?
On the first issue, Anonymouse is factually correct. Relatively few Europeans were sold into slavery (involuntary, lifelong, hereditary servitude). The main exception were the Irish whom Cromwell sold to plantations in St. Kitts, Nevis, and Montserrat. But for any text on slavery to leave out the enslavement of Native Americans is inexcusable.
On the second issue, the evidence shows that the condition of being a slave and the label associated with genetic traits of African origin became conflated in the United States during the first half of the 19th century. As anyone familiar with the topic knows, continent-of-ancestry was legally irrelevant to the condition of slavery. You were legally a slave if your mother was legally a slave, no matter what you looked like nor what "race" you were. Many slaves, of course, were of mixed ancestry, as are virtually all African Americans today. And early in the century, slaveowners had no qualms about refering to their "white" slaves, especially in ads offering rewards for the capture of runaways. Similarly, in the North, abolitionists often referred to the thousands of "white" people who were in slavery.
But around 1830-35, the terminology shifted. In 1825, a slaveowner would answer a Northern visitor's question, "Yes, she certainly is white, but she is a slave nonetheless." But by 1845, the same question would be answered, "Yes, she certainly looks white, but she is black nonetheless." In other words, the terms "black" and "white" began to move away from being purely descriptive (as they remain in Latin America today) and began to be associated with slavery itself.
This shift in meaning laid the foundation for what became the nationwide ODR a half-century later, and it had several causes. One cause was legal precedent. By 1835, at least two state supreme courts had set a law that no white person could be a slave, and other courts subsequently followed suit. The effect was not to free people with Euro ancestry, of course, but to help shift the termnology. If you were legally a slave, then you were not legally White, even if your ancestry was completely European. See
